Question

what is finite set?​

Answer 1

$\huge\blue{HELLO\:MATE}$

The empty set {} or Ø is considered finite, with cardinality zero. In combinatorics, a finite set with n elements is sometimes called an n-set and a subset with k elements is called a k-subset. For example, the set {5,6,7} is a 3-set – a finite set with three elements – and {6,7} is a 2-subset of it.
